SPECiFICATION forming part of Letters Patent No. 306,824, dated October21, 1884.

Application filed DecemberB, 1883. (No model.)

To all 10. mm, may concern:

Be it known that W6,GEORGE W. GLAZIER, a citizen of the United States,residing at Salem, in the county of Essex and State of Massachusetts,and J OI-IN B. ROLLINS, a citizen of the United States, residing atLynn, in the county of Essex, State of Massachusetts, havejointlyinvented certain new and useful Improvements in Paper Box Scoring andFolding Machines; and we do hereby declare that the same are fullydescribed in the following specification and illustrated in theaccompany ing drawings.

This invention relates to improvements in paper-box folding and scoringmachines; and it has for its object to automatically feed the box blanksor stock, one or more pieces at a time, to improved mechanism forfolding the two opposite sides'or flaps of the blank, by which such sideedges are automatically turned or folded, to enable the box-blank to beafterwardset up and united to the usual end pieces. Said boxblanks maybe scored in whole or part previous to being fed to the improvedfoldingmechanism. For instance, the blanks may be first scored in anordinary scoring-machine, both laterally and longitudinally, and thenpassed through our improved folding mechanism for turning over the sideflaps or edges; or the blank may be scored only laterally in a suitablescoring machine, and then scored longitudinally while being passedthrough our improved folding-machine. The folding-rollers are adjustableto and from each other in a horizontal direction, according to the widthof the pasteboard blank that is to be scored or folded, as willhereinafter be more fully shown and described,reference being had to theaccompanying drawings, where Figure 1 represents a plan view, and Fig.represents a side elevation of the improved machine. Fig. 3 represents afront elevation of the same. Fig. 1 represents a cross-section on theline A 13 shown in Fig. 1. Fig. 5 represents a longitudinal section onthe line 0 D shown in Fig. 1. Fig. (i represents a longitudinal sectionon the line E F shown in'Fig. 1; and Fig. 7 representsalongitndinalsection on the line G H, also shown in Fig. 1. Fig. 8 represents adetail view of the first pair of folding-rollers, and Fig. 9 representsa modification thereof for folding withrounded corners. Fig.10represents a plan view of a boxblank that is to be folded.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

a represents the frame of the machine, mounted upon and secured firmlyto suitable legs or standards, b b, as shown. The frame a has on itsupper side a pair of longitudinal and parallel guideways, a a, uponwhich the movable headstock c is adjusted to and from the stationaryhead-stock d, according to the width of the pasteboard blank the flapsof which are to be folded. The headstock (Z is firmly secured to theframe a by means of suitable belts or similar means.

6 is a screw-shaft located in bearings in the frame a, and provided inits outer end with a crank-wheel, c, by which it can be turned aroundits axis for the purpose of adjusting the position of the movablehead-stock c in relation to the stationary head-stock d, for whichpurpose said screw-shaft e is made to pass through a scrcwthreadedprojection c, on the under side of the head-stock c, as shown in Figs. 5and 6.

In suitable bushings in a slot in the stationary head-stock (l arelocated the first pair of roller-shafts, f and 9. On the inside of theheadstock d are secured to the respective shafts, f and g the rollers fand g, as shown in Figs. 5 and 1, and to the outer ends of said shafts gare secured,respectively, the pin- '85 ions f g, the teeth of which gearinto each other. Similar rollers, f 9 are splined to the respectiveshafts f g, and so journaled in bushings located in a slot in themovable head-stock 0 as to rotate with the shafts f g, 0 and also tofollow the longitudinal adjustment of the head-stock c as the latter ismoved to and from the head-stock d,- and we wish to state that we do notconfine ourselves to any particular manner of so journaling the said 5rollers f y to the head-stock d, as this may be done in any of thewell-known methods used in feeding devices for drilling or boringmachines, it being only essential that the rollers f 9 shall rotate withthe respective shafts f and g, and to follow with the head-stock c asthe latter is adjusted.

h and t represent the second pair of shafts, located in bushings in thehead-stock d, as

Iii

above described, and having attached to them on the inside ofthe'hcad-stoek (Z the respective lbldiug-rollers h and i, as shown in Fi(3. To the outer ends of said shafts 71 and t are at tached,respectively, the plnions 71 i, meshing into each other, as shown inFigs. 2 and (3. j tollers 713 t" are splined to the respective shafts I:Z. and connected to the movable headstock e in the same manner ashercinabovc described, so that said rollers 71 13 shall follow thelongitudinal adj ustmentof thehead-stock e, and also so as to rotatewith the shafts It and a".

1.: and! represent the third pair of shafts, located in suitablehearings in the stationary head-stock (I, and provided on the inside ofthe latter with the respective folding-rollers Z, and on the outside ofsaid head-stock with the respective pinions 7;2, gearing-into eachother, as shown in Figs. 2 and 7. i011- ers 7.1 t are splined to therespective shafts 7; land connected to the movable head-stock c in thesamcmanner as hcrcinabovc described, so that said rollers Z shall followthe longitudinal adjustment of the head-stock c, and also to rotate withsaid shafts 7.' and I, respectively.

m represents an intermediate loose gear meshing into the respectivepinions 1 i, and it represents another intermediate gear meshing intothe respective pinions i Z, as shown in Fig. 2, by which arrangement allthe shafts f, g, It, i, 7:, and Z are positively geared to I gethcr. Theshaft 2 is the drivingshaft, and I l l l l l t l l for this purposeprovided with. fast and loose pulleys I l", to which a rotary motion isimparted by means of a suitable belt. or cord, or similar means.

On each of the shafts 1 if, and Z is located, about midway between theirfolding-rollers, respectively, the longitudinally-adj ustable circulardisks 1 i, and 2, which serve as central rests or supports for thepasteboard blank as it is fed forward between the folding-rollers of themachine.

To the inside. of the stationary head-stockd is secured a plate or rest,at, between the lower rollers, g i, as shown in Fig. l. A simi lar plateor rest, a, is secured to the inside of stationary head-stock d, betweenthe lo wcr roll ers, 1 Z. Similar rests, m a", are secured to the insideof movable headstock 0, between the respective rollersy i" and '21 I,which plates serve as supports for the pasteboard blank while being fedforward between the rollers.

Above each of the rests in m is located the respective projections orpresscrfeet 0 0, which serve the purpose of retaining the pastcbosrdblank against the rests on m and to guide it properly between the secondsets of rollers, h '1' and f1" 2'".'

Above the rests a a" are located the curved folders p, which serve thepurpose of doub- I ling over the projecting ends or flaps of thepasteboard blank and to guide it properly between the third setsoirollers, L Z is I.

10, Q, represents the pasteboard In 1 1g.

blank that is to be folded, and q re ju'esents the end flaps orprojections that are to be folded over by our automatic machine.

Q Q are the lateral scoring-lines, and Q, Q" are the longitudinalscoringliues, on the under side of said blank, as usual.

If it is desired to make the scoring-lines (3 Q on the under side of thepasteboard blank while it is being fed through our folding mech anism,we provide thelower rollers, g g, each with an annular se .ringprojection, X, as shown in Fig. If it is desired to bond the flaps qwith rounded edges at their junction with the main part Q, we make 'thelower roll. ers, g f, with a pair of parallel annular scoringprojections, 3/ as shown in Fig. 9, and

provide the upper rollers, ff, each with an an uuiar scoring projection,Z, as shown in said Fig. 9, the latter being so located as to enterbetween the projcctitms :I/ 12 on the lower rollers.

To the front of the machine is scoured a pair of brackets, r r, havingattached to their upper ends the table or plate S, serving as a sup portfor the pile of pasteboard blanks that are to be folded.

a s are side guides for the pastcboard blanks, which guides are madeadjustable in a lateral direction to and from each other, and afterbeing so adjusted they are secured by means of screws or mpiivalentmeans to the table, s.

In front of the first set of rollers, f /f g, is secured to the table orplate 8 the horizontal beam 3, on which the stop projection s is madeadjustable in a horizontal direction.

On the stop 8 is the foot-piece 8", made ver tically adj ustable bymeans of a suitable setscrew or equivalent device, so that its lower endmay be set just so far above the plate a as to permit only one or twopasteboard blanks to be pushed forward under the foot toward and betweenthe first rollers in the machine.

For the purpose ofautomaticall y feeding one or two sheets at a timetoward the rollers, we

employ the following autonmtic feeding mcchanism, v To the shaft issecured a small pulley, 2", from which a rotary power is conveyed bymeans of a belt cr cord, t, to the pub ley t. secured to a shaft, 1",that is located in a bearing-piece. i, depending from and. secured tothe under side of the table or plate A. To the shaft 1/ is secured thegrooved cam-disk 1,, which actuates the lower end of" the rocklcver a,that is hung at u to the bearing-piece If, and is provided in itslowercnd with a pin and roll projecting into the groove on the side ofcam t, shown in Figs; 3 and 4:. To the upper end of the lever a ishiugcdthe connecting-rod c, that is jointed in its forward end to the stud r,projecting up through a slotted opening, 8', in the table 8, and securedto the sliding reciprocating l'ecd plate 12, that is thus caused to moveforward and back in suitable guides in table 8, as shown in Figs. 1 and2,. The feed-plate c has a slotted groove, 2:, in which the adjustablecarrier-plate e is ad j usted to and from the first set of rollers, andsecured in place on the feed-plate o by means of fastening-screws v orequivalent device. to compensate for the variations in length of thecard-board blanks that are to be fed to the folding mechanism. Thecarrier-plate '0 has on its upper side a ledge or projection, '0, of

i a thickness about equal to the thickness of the pasteboard blank, andit serves the purpose of automatically pushing forward the lowest sheetof pasteboards in the pile resting on the table 8, and to feed itforward below the footpiece s far enough to permit the set of rollers f5/1"" 9 to act upon said sheet, and to feed it along between thesuccessive sets of rollers for folding the blank as described. To theside guide, 8, is secured a small bracket, 10. in which the rod in isadjustable to and from the first set of rollers, and is secured in placeafter being adjusted by means ofa set-screw, w", or equivalent device,as shown in Figs. 1 and 3. To the forward end of rod 10 is secured thebar or plate 10, that serves as a back-rest for the pile of card-boardsheets during the operation of the machine, and said plate serves toprevent the card-boards from being drawn backward by the return motionof the carrier-plate t and its projection o.

The operation of this our improved foldingmachine is as follows: Thepasteboard blanks Q (shown in Fig. 10) are laid in a pile on the plateor table 3, between the side guides, s s, and between the front and rearstops, 8 and w. The machine is then set in operation, causing the lowest(or two lowest) sheet or blank in the pile to be automatically pushedforward between the first set of folding-rollers,f yf g. Each of saidrollers is made to lap by its corresponding roller, as shown in Fig. 5,by which the flaps q g on the sides of ihc blank are bent partiallyupward, (and scored on the underside, if so desired,) ac cording to theshape and bevel of such rollers. The blank continues to pass along itsflaps respectively passing between the rests m m and presser-fect 0 0,to retain the acquired bend of said flaps and to guide it properly toand between the second set of rollers, it"i" It" i, where the flaps arestill further bent upward by the increased inclines on said rollers, andafter passing by the latter the blank, with its flaps, passes betweenthe respective rests n a and curved folders p p, causing the flaps q qto be laid flat or nearly onto the main portion of the blank, afterwhich it passes between the last rollers, 7t Z n Z, for the purpose ofcompressing the flaps against the blank, and after the folded blank haspassed by the said last set of rollers the elasticity of the material ofwhich the blank is composed will cause the now liberated flaps to springupward to nearly a right angle to the main portion of the blank, whichis the proper position for securing the usual end pieces of the box tothe now folded flaps.

The automatic-feeding mechanism above described is sotimed in relationto the speed of the rollers that the blanks are automatically fedforward and carried between the foldingrollers in quick succession.

Having thus fully described the nature, c011- struction, and operationof our invention, we wish to secure by Letters Patent and claim- 1. In apape1'-box-fol(ling machine, the stationary head-stock d, with itsrotary shafts f r h t 7.: Z, and rollers f, g, h, i, 7;, and Z, combined with the adjustable head-stock 0, having journaled to it therollers f", 71?, 7?, It, and
